According to regulations, a cargo hose used for transferring liquefied gases must have a bursting pressure of __________.

Correct Answer: Option A — 5 times the maximum working pressure on the hose during cargo transfer

46 CFR 154.500 mandates that cargo hoses used for liquefied gas transfer must be designed with a minimum bursting pressure of five times the maximum working pressure. This high safety factor accounts for the extreme hazards associated with cryogenic or pressurized liquefied gas cargo.
